It is to be understood that the forms of my invention herewith shown and described,,are to be taken as preferred examples of the same and that various changes relative to the shape, size, material and arrangement of parts may be resorted to without departing from the spirit of the invention, or the scope of the subj oined claims.

Having thus described my invention, 1 claim 1. In a low slugging device, a support, :a y pair of guides positioned on said support, a p

movable bearing positioned ad j-aoen"t said guides, a cutter-headcarried by said bearing, an arm positioned on said support, a latch carried by said bearing and engaging said arm to hold said bearing in depressed posi tion with relation to said guides anda spring for moving 'said bearing away from said guides when said latch is contacted by a slug passing between said guides.

2. 111 a low slugging device, a support, a bearing movably mounted in said support, spring means interposed between said support and said movable bearing for maintaining said bearing in elevated position, a plate secured to said support and having anarmextending therefrom, a latch mechanism pivoted to said bearing and having itsnose engaging said -arin,'acutter head carried by said bearing, and a horn formed on said latch and adapted to be engagedby a slug moving into engagement with-said cutter-head;

3. In a low slugging device, a support having an armmounted thereon, amovable bearmg vertically movable on said "support, a pair of guides positioned beneath said bearing, a rotatable'cutter head carried by said bearing,spring means for normally maintaining said bearing in elevatedposition, a latch carried by said bearing and-adapted to have the nose thereof underlie'said arm .for the purpose-of holding said bearing in depressed position agalnst the 't ens on'of said spring,

and a hornformed on said latch and adapted to be engaged bya slugmoving intoengagement with said cutter head whereby said nose of said latch will be'moved out of engage ment with said arm. I i
